EPSON FX-2180 Service Manual Chapter 5 Adjustments 3. Attach the print head to the carriage assembly again and tighten the two CBS screws (3 × 10). 8. Insert a thin screwdriver into the drilled hole located at the right edge of the rear carriage guide shaft. Then adjust the platen gap by moving the screwdriver forward or backward until the gap is large enough for a 0.42 mm thickness gauge, but too narrow for a 0.45 mm thickness gauge. 4. Move the print head to the left end column position. 5.
EPSON FX-2180 Service Manual Chapter 5 Adjustments 10. If the platen gap is wider at the left end column than at the right end column, adjust the parallelism for the rear carriage guide shaft by moving the parallelism adjustment bushing backward. If the platen gap is narrower at the left end column than at the right end column, move the parallelism adjustment bushing forward. See Figure 5-4. 12. Remove the print head from the carriage assembly. 13. Insert the ribbon mask into the ribbon mask holder.
